jc-spectral-methods

An introduction to spectral methods and Julia.

Get started

Step 1: Julia installation

Install Julia

On windows, you may need to run juliaup add 1.11 from the command prompt to install the latest version. If there are permission issues when writing PATH information to your rc file, refer to the guidelines here

Step 2: Cloning repository, environment setup

Clone this repository with Github Desktop or with the command-line interface:

git clone https://github.com/qnngroup/jc-spectral-methods.git

Now, navigate to the directory you just created when cloning and start julia

$ cd jc-spectral-methods
$ julia

You should be greeted by a Julia REPL

julia>

In the Julia REPL, press ] to enter the package REPL:

(@v1.11) pkg>

Then, type activate . and press enter. This will set up an environment using the existing Project.toml configuration. Now, run instantiate to install the necessary dependencies.

Once that finishes, press backspace to return to the Julia REPL.

Step 3: running the notebook

Enter the following commands to set up IJulia for the first time:

julia> using IJulia
julia> jupyterlab()

Once IJulia finishes installing, your web browser should automatically open to localhost:8888, where the notebook is being served. It will most likely open in your home directory, so you may need to navigate around to find the location of the notebook.
